3 Claims.

1 This invention relates and especially .tools for members.

To those familiar with the zipper art it is common knowledge that the zipper teeth become bent and out of line rendering actuating of the zipper slider impossible; further, the slider may become damaged, out of line, or corroded, or the locking means on the zipper tab out of alignment or bruised thereby not looking the slider against a lace, therefore, primary object of this invention is to provide a tool whereby zipper repair may be made by correction or replacement of damaged members instead of following the common practice of replacing a complete zipto improvement in tools,

This invention resides substantially in the combination, construction, arrangement and relative location of parts, all in accordance with the disclosure herein.

"one of the jaws as viewed on the line 6, Figure 2.

Figure 7 is a view similar to Figure 2, illustrating stop means provided by closing of forward jaws, whereby, rear and lateral jaws, when in closed position, retain a slight spacing to prevent bruising of member being repaired thereby.

Figure 8 is a view of the lateral jaws broken away and viewed from their outer end.

The true nature and manner of use of a device in accordance with this invention will be best understood by a detailed description of the form thereof, shown in the drawings in an illustrative sense.

Now referring to the drawings which illustrate my preferred form of structure it will be observed that this invention includes a pair of handle members 2 and 3 of such size and shape as to be conveniently grasped in the hand of an operator, and connected by a single pivot a.

Reference to the drawings further teaches that said handles 2 and 3 carry four sets of jaw members, indicated as 5 and ii, i and 8, 5 and it, it and i2, respectively.

Jaw member 6 is formed with a central teat 14 extended outward on its outer end face and is opposed thereto in outer edge face of jaw 5 by a concaved recess l5. By providing the opposed the repairof zipper recess it is possible to straddle the zipper hinge between zipper tab and slider thereby removing danger of bruising same when clamping pres sure is placed upon the zipper locking cam by the teat M-thru means of jaw member 6. Jaw members 1 and 8 provide means for zipper tooth and zipper tab replacement, prong 20, Figure 8, being wedged, on closing of the jaws l and 8, between the zipper tooth and tape thereby prying said tooth free of the zipper" tape for removal therefrom and substitution of an operable tooth. In replacing a zipper tooth same is inserted .in one of the .slots 2], which are of varied depth, .on either jaw, depending .on size .of tooth, the fastening prongs which secure the tooth to the tape being open, zipper tooth is then set to the zipper tape and clamped thereto, purpose of the opposed slots being to retain the zipper tooth straight to the Zip r tape while being engaged therewith. For zipper .tab replacement the zipper tab 'hinging prongs are set in hinge socket of the slider and clamped into position by inserting tab between slots 23 and 24 then manually holding the slider so that the hinge socket is between tab jhinging prongs, then clamping the prongs into the socket, however in this operation care must be exercised not to crush either the zipper prongs or zipper socket which would destroy pivotal relation therebetween, therefore observation of Figure 7 will teach that complete closing of jaw members 1 and 8 is prevented, a space corresponding to the width of the socket being maintained by step means provided by jaw members 5 and 6 which are timed by reason of their structure and pivotal relation of members 2 and 3 to completely close simultaneously with the jaw members I and 8 reaching the defined space relationship.

When zipper slider fails to lace, requiring removal by jaw members II and I2 for repair or replacement, the zipper must be laced for replacement of zipper slider, therefore, I provide jaw members 9 and I 8, the opposed faces having central recesses, 26 and 21, respectively, running lengthwise of the jaws with inner end curved outward, Figure 5, which, when jaws are applied to the zipper and slid thereover, act as a zipper slider, the curved ends being means to urge the opposed zipper teeth together, care must be exercised not to bruise or crush the teeth, therefore, spacing corresponding to the elevation of the zipper teeth is provided for in a like manner and simultaneous with the spacing of jaw members i and 8 by the stops or jaw members 5 and 6.

Jaw members H and 12 comprise the pin shaped jaw member ll having a head 13, said member being in central transverse relation to and slidably traversing nose portion 30, for action to and from jaw member i2, extended to inner face of nose member 3!, actuated by said member to and from jaw member 12, during use of the tool, and circumscribed by a coil spring 32 between the opposed nose portions, said spring forming means to return and hold the tool in inactive position, Figure 2, and opposed by jaw member 12 of wedge shaped bill structure with the bill point in vertical alignment with center of pin head I3, and normally spaced thereabove sufficient to insert a zipper slider, end to end,

therebetween, with the closed end resting on pin 1. levers arrangedior alignment with each other head 13 and its open end in position to receive,

the wedging bill to spread the zipper slider for removal from a jammed position, slider or for removal of zipper placement. e i

From the above description it will be apparent to those skilled in the art that the details of construction illustrated herein may readily be varied without departure from the novel subject matter herein disclosed. I do not, therefore, desire to be strictly limited by the disclosure but rather by the claims granted me.

What is claimed:

1. A tool of the kind described, comprising a pair of crossed pivotally connected operating levers arranged for alignment with each other in their crossed relation, opposed portions of one end of the levers extending laterally thereof and forming stops, a wedge shaped bill element car- 'ried by one of the levers, and

projected laterally at substantially right angles thereto from an outer face of the same, and a displaceable member carried by the other lever and having an anvil head opposed to and coacting with the bill element on operating the leversm 2. A tool of the kind described, comprising a pair of crossed pivotally connected operating levers arranged for alignment with each other in their crossed relation, opposed portions at one end of the levers extending laterally thereof and for resetting of slider for re- 1,421,871 Wagner in their crossed relation, opposed portions at one end of the levers extending laterally thereof and formingstops, a'wedge-shaped bill carried by and projecting laterally and at substantially a right angle to the outer face of one lever, and a displaceable member carried by the other lever and extending laterally in the same general direction as said wedge-shaped bill, said displaceable member having an anvil head thereon opposed to and coacting with said bill upon operating said levers.
